I have the same issue. Also `Select Serial Port` in the lower right corner doesn't work. With `Adafruit CircuitPython 8.1.0-beta.2-31-g827eaeb1f on 2023-05-12; VCC-GND YD-ESP32-S3 (N16R8) with ESP32S3` the Serial Monitor...
I finally figured out the problem. It is because the power source is a 3.3V LDO. It works well with a single LCD or WiFi module. However, when they work...

Totally same issue with esp32c3
